CPU, GPU, Northbridge..........

[Ct. Strangelove]

What is eveyone's experiences at cooling the CPU, GPU, and northbridge?

What kind of setup of piping? Any temperature problems?
I have a 226w pelt that will be used
The 3 WBs are of a Danger Den brand.
I have two BIX (only one i should need)
Ehiem 1060. (which i am very pleased with)

I am concerned with flow rate. I have a few other deviced to be cooled, ie HD, PS.

I want HIGH flow throught the blocks but i want SLOW flow through the RAD. How can i do this? CAn i even do this?

I am on the right track? THx

If I were doing what it seems you are planning on doing with that picture you got there........................

I would probably keep with the 5/8 feed and go to 1/2 for the CPU and only 3/8 for the other two. Also if you want to lower your flow rate for the radiator but keep it high for your blocks, have a large return line. Say if you have a pressure line of 5/8, then make your return line, say 3/4 or maybe even bigger. That way your water slows down in the larger line and can move slower through the radiator before it is "pushed" back into the system through the pressure line.

Reason why I say that is because I have been observing the heatercores on some cars recently and have noticed that almost all of them have a larger return line that the pressure line. Also the same way in hydrolic pressure systems. Small pressure line for higher pressure and flow but larger return line for volume over flow rate.

Like always, feel free to correct me if I am wrong....

All that sounds good.
So i shold try useing 3/8 for the GPU/northbrigde?
If so, that would keep high pressure though the GPU/northbridge and just a little less pressure (but a little higherflow) through the CPU. But the connectors in the BIX are 1/2". If i have two BIX in series the flow rate should be a lot slower (but not halfed).
The return line of the Ehiem 1060 in a whopping 1". I would be going from 2 1/2" directy into 1".

thanks I have some new light to work with.

Run the BIX in parrallel.... you will get much better performace. Running blocks in series is alright but definately run your radiators in parrallel. Reason: radiators work the best when the difference between the water temp and ambient are greater. In series, you are cooling the water down and then trying to cool it down some more when it is already cooler; hence the second radiator will only be running at say 25-50% efficency. Running them in Parrallel will deliver maximum difference to both and decrease the time in both radiators at the same time!

Also reason why you want a larger pressure line to the CPU block is because that is where the most water flow is needed (higher heat disapation). The other blocks combined dont even put out 1/4 of the heat that your Pelt + CPU will be putting out.

hehe if you can do a full 1" return line, ! would say Go For IT! couldnt hurt. But keep your pressure line smaller for sure.

I was thinking of getting two slow pumps and running two rads parralell, but only on a curcuit with the res'. for the I'd use CPU use a bigger pump that matches or passes the performance of the two weaker pumps.
